# BNNSGraphGetArgumentNames(_:_:_:_:)

Extracts the names of arguments for the given function argument.

## Declaration

```swift
func BNNSGraphGetArgumentNames(_ graph: bnns_graph_t, _ function: UnsafePointer<CChar>?, _ argument_names_count: Int, _ argument_names: UnsafeMutablePointer<UnsafePointer<CChar>?>) -> Int32
```

## Parameters

- `graph`: The compiled graph object.
- `function`: The function. Specify as nil if the graph only contains one function.
- `argument_names_count`: The number of elements in the argument_names array.
- `argument_names`: On output, an array of pointers to strings that contain the argument names.

## Return Value

Return Value 0 on success, nonzero on failure.

## Discussion

Discussion This function is the equivalent of the concatenation of BNNSGraphGetOutputNames(_:_:_:_:) and BNNSGraphGetInputNames(_:_:_:_:).
